May, Yuki and Lenny start their first shift after Heather's death. Adam patches them off with Zoe and she takes Lenny, Jeff and Polly take Yuki and Ruth takes May. They eventually are asked to sit out. At the end of the day the three go to a counselling session with Ben Harding. He describes May as the Scarecrow (no brain), Lenny as the Tin Man (no heart) and Yuki as the Lion (no courage) from The Wizard of Oz. Meanwhile Zoe is neglecting her work to take mysterious calls about Nick Jordan and an old face returns.
